Gastrointestinal Bleeding

This study aims to compare the clinical outcomes between routine use of potassium competitive acid blocker (P-CAB) and guideline-directed gastrointestinal (GI) protection strategy in patients with acute myocardial infarction (AMI) undergoing percutaneous coronary intervention (PCI) and being treated with dual antiplatelet therapy (DAPT).

The objective of the study is to investigate the treatment of marginal ulcers with Low Thermal plasma in an endoscopic setting. By a treatment of the ulcerated areas with argon plasma with low power settings (\~ 1 W) we hypothesize that the size of the ulcers will shrink, and the healing is accelerated compared to standard of care alone. Patients will benefit from this minimally invasive approach compared to a much more invasive surgical approach that comes with higher risks and hospital stay length time. From a societal and scientific perspective, this study aims to extend the well-documented clinical benefits of plasma technology - from external wound healing to internal ulcer treatment - within an endoscopic framework. The success of this study could pave the way for broader applications of LTP in the treatment of other endoscopically accessible conditions such as peptic ulcers, duodenal ulcers and esophageal ulcers. This advancement has the potential not only to improve patient outcomes through less invasive methods, but also to position LTP as a cornerstone in the future of gastroenterological wound management strategies.

Small bowel capsule endoscopy is the main diagnostic standard for small bowel bleeding. This study investigates the detection rate of small bowel bleeding in capsule endoscopy and further endoscopic treatment in a prospective and retrospective cohort.

Upper gastrointestinal bleeding (UGIB) is a common and potentially lethal medical emergency, which requires hospitalization and healthcare resources. Despite the changing epidemiology and advancement of endoscopic therapy in the recent decade, the all-cause mortality of UGIB remains high (\>2%). An accurate risk stratification is necessary to triage patients into low- or high-risk groups, in order to inform clinicians for the necessity and timing of urgent endoscopy. However, existing pre-endoscopy risk scores, such as the Glasgow-Blatchford score (GBS), Rockall score and AIMS65 score, are suboptimal in predicting relevant clinical outcomes. An alternative strategy for risk stratification is urgently warranted in patients with UGIB to guide the next step of management. In a pre-clinical study, the sensitivity and specificity of HemoPill® prototype were 95% and 87.5% respectively, when the sensors were positioned close to the bleeding point. Furthermore, several human clinical studies have proven the feasibility and accuracy of HemoPill® in healthy volunteers and patients with suspected UGIB. Capsule ingestion was well tolerated with no device-related adverse event or capsule retention. All patients with negative HI were found to have no active endoscopic bleeding (true negative, 100%, 17/17). In patients with bleeding \>20ml, true positive HI signals were detected (100%, 2/2) In a retrospective multi-center study, 61 patients with suspected UGIB were recruited to use HemoPill®. Among the capsule-positive cases, subsequent endoscopy confirmed active bleeding in 57% (20/35) of them. None of the capsule-negative patients rebled (0%, 0/25), which prevented unnecessary emergent endoscopy in 72% of them (18/25).

The goal of this observational study is to evaluate the diagnostic value and safety of capsule endoscopy in patients with gastrointestinal bleeding. The main questions it aims to answer are: What is the overall detection rate of bleeding lesions using capsule endoscopy? What is the completion rate of capsule endoscopy, and how long does it take for the capsule to pass through the stomach and small intestine? What adverse events (such as capsule retention) occur during or after the procedure? Participants who underwent capsule endoscopy for gastrointestinal bleeding at Changhai Hospital between January 2021 and December 2025 will: Have their existing medical records (including endoscopy reports, procedure notes, and follow-up records) reviewed by researchers Have their personal information anonymized and protected Not be required to undergo any additional tests, procedures, or visits This is a retrospective study that only analyzes previously collected data. No new interventions or patient contact is involved.

Can physiological indicators such as quick Sequential Organ Failure Assessment , Shock Index, and its derived indicators such as Modified Shock Index , Age Shock Index and Respiratory Adjusted Shock Index accurately predict the prognosis of cirrhosis patients with gastrointestinal bleeding? To explore the improvement of emergency and critical care patient management.

The goal of this clinical trial is to evaluate the clinical efficacy and safety of YiWei Jiaohuang Ointment in treating gastrointestinal bleeding associated with oral antithrombotic therapy. The main question it aims to answer is: Does Yiwei JiaoHuang Ointment accelerate the conversion to negative results in fecal occult blood tests among patients with gastrointestinal bleeding associated with antithrombotic therapy? Researchers will compare use rabeprazole alone as routine therapy to see if Yiwei JiaoHuang Ointment can accelerate the conversion to negative results in fecal occult blood tests. Participants will ： Take Yiwei JiaoHuang Ointment every day for 2 weeks. Return to the hospital for a fecal occult blood test after 3 days, 1 week, and 2 weeks of medication.

Gastrointestinal bleeding (GIB) is a common emergency in hepatology and gastroenterology, with an overall mortality rate ranging from 5% to 10% depending on the study. GIB is classified into two categories: upper GIB (80% of cases) and lower GIB (20% of cases). There are many risk factors for GIB, including anticoagulants. In cases of GD under anticoagulants, there are specific management recommendations. In particular, in cases of severe bleeding under direct oral anticoagulants (DOACs), it is recommended to stop treatment and correct coagulation parameters according to the severity of the bleeding and the associated thrombotic risk. Various treatments can be used for this purpose, including specific antidotes, fresh frozen plasma, and prothrombin complex concentrate (PCC). However, the role of PCC in this indication is uncertain, as is the efficacy and safety data for this drug, due to significant methodological limitations in the few studies conducted on the subject.

Blood thinner medications used for cardiovascular disease can cause gastrointestinal bleeding. Early detection of invisible bleeding by performing occult fecal blood test (called fecal immunochemical test, or FIT) can uncover serious disease in the stomach and intestine and enable the treating physician to refer the patient for further evaluation.

Acute gastrointestinal bleeding is potentially lethal in liver cirrhosis. Accurate assessment of prognosis is critical in a timely fashion. A novel model, CAGIB score, has been developed based on our Chinese multicenter retrospective study. Now, a prospective, international multicenter, observational study will be performed to further compare the performance of CAGIB versus Child-Pugh and MELD scores for evaluating the in-hospital mortality of patients with liver cirrhosis and acute gastrointestinal bleeding.

PANTHER-GI Pilot Study will assess the feasibility of a full-scale multicentre cohort management study evaluating the safety of a standardized strategy for resuming direct oral anticoagulants (DOACs) after major DOAC-related gastrointestinal (GI) bleeding among patients at moderate to high risk of re-bleeding and thrombosis. A parallel registry will assess whether eligible patients who are not enrolled in the PANTHER-GI Pilot Study are systematically different than enrolled patients and to explore barriers to enrolment.

The Comprehensive HHT Outcomes Registry of the United States (CHORUS) is an observational registry of patients diagnosed with Hereditary Hemorrhagic Telangiectasia (HHT). The purpose of this study is to better understand HHT, the symptoms and complications it causes, and the impact the disease has on people's lives. The investigators will collect long-term information about the participant, allowing us to understand how the disease changes over time, and what factors can influence those changes. Ultimately, this should help improve treatments for the disease. Another important goal of the study is to provide a way to contact people to participate in future clinical trials and other research. The registry will be a centralized resource for recruitment for clinical trials. People in the registry will not be obligated to join any of these additional studies, but if interested, can agree to be contacted if they may be eligible for a study. Participants will: * Be asked to provide permission to collect information from their medical records, including things like demographic information, diagnosis information, family history, test results, treatment information, symptoms, complications, lifestyle and other relevant medical information. * Be asked study-related questions by phone or at a clinic visit. * Be asked study-related questions every year after enrollment for up to 10 years or until the study ends. A member of the study team will communicate with participants by phone or at clinic visits to collect information regarding any changes to their health over the previous year/s including new test results, treatment information, symptoms, and complications from HHT.

Anemia is a frequent complication of gastrointestinal bleeding, affecting 61% of the patients. Currently, anemia caused by gastrointestinal bleeding can be treated with iron supplementation. However, the dose and route of the administration are still a question. The FIERCE clinical trial aims to compare the effect of intravenous iron supplementation and oral iron replacement on mortality, unplanned emergency visits, and hospital readmissions in multimorbid patients with acute nonvariceal gastrointestinal bleeding.

The goal of this clinical trial is to explore the diagnostic efficacy of detachable string magnetically controlled capsule endoscopy (ds-MCE) for identification of bleeding lesions in patients with antiplatelet drugs-related acute non-hematochezia gastrointestinal bleeding. The main questions it aims to answer are: Compared to the conventional esophagogastroduodenoscopy, does ds-MCE accurately detect bleeding lesions in the upper gastrointestinal tract in patients with antiplatelet drugs-related acute non-hematochezia gastrointestinal bleeding? Recording bleeding lesions in the small bowel detected by ds-MCE in patients with antiplatelet drugs-related acute non-hematochezia gastrointestinal bleeding. Participants will: Undergo ds-MCE first and subsequently EGD within 24 hours. Receive follow-up in the following 30days.

This study aims to investigate whether atmospheric pressure has an effect on upper gastrointestinal bleeding (UGIB), which includes causes such as peptic ulcer disease, esophagitis, gastritis, gastrointestinal varices, Mallory-Weiss tears, and gastric cancer. The goal is to determine the impact of atmospheric pressure and gather information on its role in high-risk UGIB.

Severe and un-stopped blood loss can occur for a number of different reasons including after a serious injury, delivery of a baby and following other medical and surgical emergencies. The investigators understanding of how to best treat people with serious bleeding is still incomplete, with many questions remaining. These include questions regarding how many people have serious bleeding events, what happens to them and the best way to treat them. The Massive Transfusion Registry (MTR) is a register of patients who have experienced major blood loss that required a massive transfusion in any clinical setting. The MTR uses electronic data extraction and data linkage methodologies. Pre-existing clinical data from hospital data sources, including Laboratory Information Systems (for transfusion history and laboratory results) and Health Information Services databases (for Patient demographics and admission data), are electronically extracted by staff employed at the participating hospitals. The data is then sent to the MTR Research Team, located at Monash University, where it is then linked, analysed and stored. The establishment of a Massive Transfusion Registry will be a unique and important resource for clinicians in Australia, New Zealand and internationally, for Blood Services and for the broader community. It will provide valuable observational data regarding the types and frequency of conditions associated with critical bleeding requiring massive transfusion, the use of blood component therapy (i.e. ratios and quantities of different types of red cell to non- red cell components) and patient outcomes.
